The Nobel Prize in Physiology or Medicine 2012

Awarded jointly to Sir John B. Gurdon and Shinya Yamanaka "for the discovery that mature cells can be reprogrammed to become pluripotent."

John Gurdon (a UK scientist) in the 1960's used a frog egg and cells from an adult frog to show that the adult cell nucleus can replace the egg nucleus and then develop normally into a tadpole then frog.

  • Shinya Yamanaka (a Japanese scientist) in 2006 identified just 4 proteins are required to turn any cell into a stem cell.
